You've made the most of the season. Now make sure winter doesn't set you back. This -100°F antifreeze keeps your RV, boat, or EV water system protected through deep freezes, so everything works like it should when it's time to roll.

Features to know about

Extreme Cold Protection

When temperatures drop, you need antifreeze you can trust. This -100°F formula protects your RV, boat, or EV water system during long-term subzero storage. It's alcohol- and glycerin-free, so it won't dry out seals or leave behind an odor, and it helps prevent corrosion so your system works properly when spring returns.

What is Burst Point vs. Freeze Point?

Antifreeze labels can be confusing. The -100°F rating reflects burst point, the point where treated lines won't crack or split, not the temperature where the fluid stays liquid. In extreme cold, lesser blends can start to slush, but this premium formula stays stable through the coldest nights and harshest storage conditions, so your system is ready when spring rolls around.
